 Mexico and California. 



4- *- Leaves rigid, destitute of woolly or cobwebby hairs, the margins naked or 

 ciliate with rigid or rather soft hairs: plants either densely or loosely tufted : 

 the leaves mostly less crowded. 



5. P. csespitosa, Nutt. Leaves linear-subulate or oblong-linear, commonly 

 much crowded, hispid-ciliate, otherwise glabrous or with some short glandular- 

 tipped hairs : corolla with tube somewhat exceeding the calyx. — Jour. Acad. 

 Philad. vii. 41. Mountains of Colorado, Montana, and westward. Occurs 

 under several dwarfed forms. 



6. P. Douglasii, Hook. Less densely tufted, either pubescent or nearly 

 glabrous : leaves acerose or narrowly linear subulate, less rigid and usually less 

 crowded, often spreading, their margins hirsutely ciliate next the base or naked : 

 flowers subsessile or short-peduncled : corolla (purple, lilac, or white) with tube 

 exceeding the calyx. — From Montana to Utah, Colorado, and westward. 



Vav. longifolia, Gray. A rigid form, of more arid regions, and long and 

 nanow less fascicled leaves. — Proc. Am. Acad. viii. 254. W. Nebraska to 

 Oregon and California. 



* * Loosely tufted or many-stemmed from a merely woody-persistent base, with 

 linear or lanceolate spreading leaves, which are little if at all fascicled in the 

 axils : flowers slender-peduncled. 



7. P. longifolia, Nutt. Nearly glabrous or pubescent, much branched or 

 many-stemmed, 3 to 8 inches high : leaves mostly narrowly linear, 1 to 2£ 

 inches long: calyx more or less angled by the white-membranaceous replicate 

 sinuses: lobes of the rose-colored or white corolla obovate- or oblong-cuneatei 

 entire or retuse : style long and slender. — Jour. Philad. Acad. vii. 41. From 

 Colorado to Montana and westward. 



Var. brevifolia, Gray. A depressed or dwarf form ; with leaves 3 to 

 4 lines long, rigid and with more cartilaginous margins, at least the lower 

 lanceolate or ovate-lanceolate. — Proc. Am. Acad. viii. 254. 



8. P. nana, Nutt. Glandular and roughish-pnbescent, loosely and copi-

 characters have failed. — Gray, Proc. Am. Acad. viii. 261 ; Ibid. xvii. 223,
